Description

Technical Field

[0001] This invention belongs to the field of marine power generation technology, specifically relating to a solar-wave power generation device for strong wave sea areas. Background Technology

[0002] Traditional offshore photovoltaic (PV) and wave energy power generation are two important ways to utilize marine renewable energy. Offshore PV has significant advantages such as high power generation efficiency and saving land resources, while wave energy power generation has the characteristics of high energy density, high predictability, and strong periodicity, and is one of the main directions for the future development of clean energy.

[0003] Currently, wave power generation primarily utilizes the horizontal or vertical impact of waves to power generators. Because the vertical impact energy of waves is relatively greater than that of horizontal waves, especially in the case of large or long waves, the amplitude of the wave fluctuations is more significant, resulting in higher energy density. Therefore, existing wave power generation methods mainly utilize the vertical impact of waves, including oscillating buoys and oscillating water columns. The oscillating buoy's power generation principle is based on the vertical impact of waves causing the floating platform to move up and down, driving airflow. The oscillating water column's power generation principle is based on the vertical impact of waves causing an air column to fluctuate up and down, generating airflow, which then drives a turbine to generate electricity.

[0004] Wave energy generation devices such as oscillating floats and oscillating water columns float on the sea surface using a floating structure and are anchored to the seabed or foundation structure by mooring cables, thus preventing the device from deviating from its working area due to wave impact. However, these devices require a certain amount of internal space to generate airflow, resulting in a relatively large size. When floating on the sea surface, they are prone to capsizing when impacted by waves, leading to poor stability of existing wave energy generation devices. Summary of the Invention

[0008] Preferably, there are multiple annular drive rings, which are arranged layer by layer at equal intervals along the radial direction of the support. The multiple annular drive rings are coaxial with the vertical center line of the support. The length of the connecting arm on the multiple annular drive rings gradually increases from the outside to the inside. The distance between the outer edge of the wave plate on the multiple annular drive rings and the vertical center line of the support gradually decreases from the outside to the inside. The tension rope passes through the connecting ring on each annular drive ring layer by layer from the outside to the inside and is fixedly connected to the last connecting ring on the innermost annular drive ring.

[0009] Preferably, a U-shaped force-bearing connecting pipe is fitted on the side of the connecting arm away from the support, and the two ends of the Y-shaped connecting rod are fixedly connected to the U-shaped force-bearing connecting pipe.

One end of the cantilever connecting rod is fixedly connected to the U-shaped force-bearing connecting pipe, and the other end is fixedly connected to the wave-receiving plate.

[0010] Preferably, edge sealing clamps are respectively fitted at the connection points of adjacent connecting arms. The edge sealing clamps are connected to the connection points of adjacent connecting arms by fasteners. A connecting shaft is horizontally provided directly above the top of the edge sealing clamp. Clamping platforms are fixed at both ends of the connecting shaft and are perpendicular to each other. The clamping platforms are fixedly connected to the top of the edge sealing clamp. A ring is fitted on the connecting shaft and is rotatably connected to it. One side of the ring is fixedly connected to the bracket.

[0011] Preferably, the longitudinal section of the wave-receiving plate is arc-shaped, the centerline of the wave-receiving plate is located on the lower side of the arc, and the centerline of the wave-receiving plate intersects perpendicularly with the centerline of the annular drive ring.

[0012] Preferably, the support includes: an upper disk, a lower disk, and multiple main connecting rods.

[0028] This invention provides a solar-wave energy generation device for strong wave sea areas, which is described below in conjunction with... Figures 1 to 9 The present invention is illustrated by the structural diagram shown below.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Reference Figure 1 , Figure 1 This is a perspective view of the power generation device in this embodiment. A solar-wave power generation device for strong wave sea areas includes a support frame and multiple floating cylinders 3 mounted on the support frame. The multiple floating cylinders 3 are evenly spaced around the outside of the support frame to allow it to float on the sea surface. The bottom of the support frame is anchored by a mooring cable 6. It also includes a generator 8 and a wave-driven structure. The generator 8 is mounted on the support frame. The wave-driven structure includes: a tension rope 15, multiple connecting arms 14, and multiple wave-receiving plates 5. The multiple connecting arms 14 are evenly spaced around the bottom of the support frame with the vertical centerline as the center. Arm 14 is arranged radially downwards at an angle. One end of the connecting arm 14 is hinged to the support. Multiple wave-receiving plates 5 are horizontally arranged at the other end of the connecting arm 14 in a corresponding manner. The vertical impact of the waves causes the connecting arm 14 to swing up and down through the wave-receiving plates 5. One end of the tension rope 15 is connected to the generator 8, and the other end passes through the side of the connecting arm 14 closest to the wave-receiving plate 5 in sequence. The tension rope 15 is slidably connected to the connecting arm 14 along the direction of penetrating the connecting arm 14. The tension rope 15 is fixedly connected to the last connecting arm 14. The up and down swing of the connecting arm 14 pulls the tension rope 15 so that the tension rope 15 drives the generator 8 to generate electricity.

[0031] This embodiment of the photovoltaic-wave energy generation device for strong wave sea areas is a wave energy capture and power conversion system based on the principle of mechanical linkage. Its core lies in converting the vertical impact kinetic energy of irregular waves into periodic pulling motion, thereby driving the generator 8. The entire device is provided with sufficient buoyancy by the floating cylinders 3, allowing the support structure to float on the sea surface. Positional stability is achieved with the mooring cable 6 anchored at the bottom, preventing drifting or capsizing. The support structure, as the main load-bearing component, not only supports the floating cylinders 3 and any potential photovoltaic equipment, but also provides the installation foundation and rotation fulcrum for the wave-driven structure below. Multiple floating cylinders 3 are evenly spaced around the outside of the support structure, forming a uniform buoyancy layout, which helps maintain the device's center of gravity balance and enhances overall stability. One end of the mooring cable 6 is connected to the central area at the bottom of the support structure, and the other end is fixed to the seabed anchor point, forming a tension constraint system that restricts the lateral displacement of the power generation device while allowing a certain degree of vertical undulation, thus adapting to dynamic wave changes.

[0032] The wave-driven structure is a key module for capturing wave energy. Multiple connecting arms 14 are arranged in an array around the vertical centerline of the support frame, with each arm 14 radiating downwards from the bottom of the support frame, forming a radial geometric configuration. This arrangement allows each wave-receiving plate 5 to cover a large area of ​​water, increasing the wave impact range of the wave-driven structure. One end of each connecting arm 14 is hinged to the support frame, allowing it to swing up and down around the hinge point. This flexible connection avoids stress concentration problems in rigid structures under impact loads, improving durability. The wave-receiving plate 5 is horizontally installed at the end of the connecting arm 14 furthest from the support frame, directly facing the vertical impact of the waves to receive the upward wave impact force. When a wave crest passes, the water pushes the wave-receiving plate 5 upwards, causing the connecting arm 14 to swing upwards; when a wave trough arrives, gravity and water settling cause the connecting arm 14 to fall back, creating a reciprocating motion. The up-and-down swinging process of the connecting arm 14 simulates the power transmission behavior of a lever mechanism, converting wave kinetic energy into mechanical swing kinetic energy.

[0033] The tension rope 15 serves as the power transmission medium, with one end connected to the generator 8 and the other end passing through the connecting arms 14 sequentially near the wave-receiving plate 5, and fixedly connected to the last connecting arm 14. The tension rope 15 is made of high-strength, high-toughness, and high-wear-resistant steel rope. The tension rope 15 has a sliding connection with the connecting arms 14, allowing it to slide along the direction through the connecting arms 14 without being bound, but it is rigidly anchored to the last connecting arm 14 at its end. As multiple connecting arms 14 swing successively or synchronously under the action of waves, their superimposed motion periodically pulls the tension rope 15, producing a "pulling rope" reciprocating traction action. This multi-point coordinated pulling mechanism can effectively accumulate small local displacements, increasing the pulling stroke of the tension rope 15, thereby improving the work capacity of the generator 8 per unit time. The generator 8 is installed inside the support or on the lower structure, receiving mechanical input from the tension rope 15 and converting it into electrical energy output.

[0034] Specifically, the generator 8 is equipped with a self-resetting shaft, which is connected to the tension rope 15. That is, as the wave weakens and the wave-driven structure returns to its original state, the shaft can automatically retract the slack tension rope 15 and tighten it again to ensure the integrity of the next effective pulling stroke.

[0035] The components described above exhibit clear functional division and spatial coordination: the float 3 ensures the stability of the device's floating state and attitude; the mooring cable 6 provides positioning constraints; the wave-sensing plate 5 captures wave kinetic energy; the connecting arm 14 amplifies torque and converts motion; the tension rope 15 concentrates energy and transmits it over long distances; and the generator 8 ultimately completes the energy conversion. The entire power generation device requires no external power source, relying entirely on natural wave excitation to generate electricity autonomously, making it suitable for deep-sea or near-shore areas with strong waves far from land.

[0036] The above embodiments achieve efficient capture and stable conversion of irregular vertical wave energy in strong wave environments. Due to the combination of multiple connecting arms 14 and wave-collecting plates 5, the device possesses omnidirectional wave response capability, maintaining continuous power generation even in sea areas with frequently changing wave directions. The tension rope 15 passes through multiple connecting arms 14 and is fixed only at the ends, allowing the swing excitation of multiple connecting arms 14 to be linearly superimposed and transmitted to the same generator 8, significantly improving energy harvesting efficiency. Simultaneously, the overall structure has a low center of gravity and uniform buoyancy distribution, and with the bottom anchoring design, it greatly enhances anti-overturning performance, enabling long-term reliable operation under high sea state conditions.

[0037] Reference Figure 8 , Figure 8 This is a schematic diagram of the interconnected structure of the connecting arms 14 in this embodiment. As a further optimization, the connecting arms 14 in this embodiment are U-shaped. The ends of adjacent connecting arms 14 are connected to each other to form an annular drive ring. The connection point of adjacent connecting arms 14 is hinged to the bracket. A Y-shaped connecting rod 21 is provided on the side of the connecting arm 14 near the wave plate 5. The Y-shaped connecting rod 21 is arranged inclined upward. Both ends of the Y-shaped connecting rod 21 are connected to the connecting arm 14, and a connecting ring 17 is fixed at the other end. The center line of the connecting ring 17 is tangent to the circumference of the annular drive ring. The tension rope 15 passes through the connecting ring 17 in sequence and is fixedly connected to the last connecting ring 17.

[0038] In this embodiment, U-shaped connecting arms 14 are connected end to end to form a closed annular drive ring, which, together with the Y-shaped connecting rod 21 and the connecting ring 17, achieves efficient force transmission and improved structural stability under wave excitation. The U-shaped connecting arms 14, as the basic mechanical unit, have their openings facing the support and are made of high-strength, high-toughness alloy materials, such as Q345 alloy steel or 316L stainless steel, possessing excellent fatigue resistance and seawater corrosion resistance. The two arms of each U-shaped connecting arm 14 are parallel or slightly outwardly flared, ensuring sufficient structural strength and spatial adaptability when connected to the Y-shaped connecting rod 21. The ends of adjacent U-shaped connecting arms 14 can be integrally formed, thus constituting a continuous annular mechanical frame—the annular drive ring. This structure can deform in a coordinated manner as a whole when subjected to asymmetric wave impact.

[0039] The connecting nodes of the annular drive ring (i.e. the connection points at the ends of adjacent U-shaped connecting arms 14) are connected to the bracket by a hinge. This hinge structure allows the connecting arms 14 to swing periodically in response to the wave undulations of the wave-receiving plate 5, while limiting their lateral displacement, ensuring the predictability of the motion trajectory and the reliability of the transmission.

[0040] A U-shaped connecting arm 14 is positioned near the wave-receiving plate 5, with a Y-shaped connecting rod 21 inclined upwards. The two ends of the Y-shaped connecting rod 21 are fixedly connected to the U-shaped connecting arm 14, while the other end extends to the outside of the annular drive ring and is fixed with a connecting ring 17. The Y-shaped connecting rod 21 can be manufactured using a forging process, and the material can be selected as high-strength aluminum alloy or titanium alloy, achieving strength while reducing overall weight.

[0041] The connecting ring 17 is fixed to the top of the Y-shaped connecting rod 21. Its geometric center line is tangent to the circumferential direction of the annular drive ring. When the annular drive ring swings up and down with the waves, the connecting ring 17 also swings up and down synchronously. Since the tension rope 15 passes through the connecting ring 17 along the circumferential direction of the annular drive ring, it can minimize the lateral friction and bending stress between the tension rope 15 and the connecting ring 17, reduce the risk of wear, and extend the service life.

[0042] The tension rope 15 is a high-strength, flexible traction element, which can be made of galvanized steel wire rope, synthetic fiber composite cable, or carbon fiber reinforced cable, possessing high tensile strength, corrosion resistance, and low creep characteristics. One end is connected to the drum or shaft of the generator 8, and then passes sequentially through the connecting rings 17 on each Y-shaped connecting rod 21, finally being fixedly connected to the last connecting ring 17. This "threading + end fixing" method allows the tension rope 15 to be continuously pulled during the oscillation of the annular drive ring, forming a reciprocating motion, thereby driving the generator 8 to generate electricity. Since multiple connecting rings 17 are evenly distributed on the annular drive ring, the tension rope 15 can achieve multi-point guidance during movement, further enhancing operational stability.

[0043] In this embodiment, the U-shaped connecting arms 14 are interconnected to form a ring drive ring, integrating the originally independent swing units into a unified motion structure, significantly improving the overall stiffness and torsional resistance. The Y-shaped connecting rod 21, as a force converging structure, concentrates and transmits the distributed swing torque to the connecting ring 17. The connecting ring 17 ensures that the force direction of the tension rope 15 is consistent with the motion direction, reducing energy loss. The tension rope 15 passes through multiple connecting rings 17 and is locked at the end, forming a stable and reliable mechanical transmission chain. Under wave excitation, the entire system can transform irregular up-and-down oscillating motion into orderly linear pulling motion, achieving efficient conversion of mechanical energy into electrical energy.

[0044] This embodiment achieves stable capture and efficient transfer of wave kinetic energy in a strong wave environment. The use of U-shaped connecting arms 14 connected end-to-end to form a ring drive circle results in a more uniform force distribution, preventing breakage or failure of a single connecting arm 14 due to localized overload. Furthermore, the inclusion of a Y-shaped connecting rod 21 and a connecting ring 17 whose centerline is tangent to the ring drive circle ensures a reasonable force direction for the tension rope 15 during movement, reducing friction loss and the risk of off-center loading. Combined with the arrangement of the tension rope 15 passing through multiple sets of connecting rings 17 and fixed at the end, the stability and response sensitivity of the traction process are improved. This effectively solves the technical problems of easily damaged transmission structures, low energy transfer efficiency, and unstable operation in traditional wave energy devices, achieving the technical effects of improving device reliability, extending service life, and enhancing power generation continuity.

[0045] Specifically, in this embodiment, the upper diameter of the annular drive ring is smaller than the lower diameter, which facilitates the overall rotation of the annular drive ring. During the upward rotation of the annular drive ring, the tension rope 15 is quickly stretched, thereby driving the generator 8 to generate electricity.

[0046] Reference Figure 3 , Figure 4 as well as Figure 6 , Figure 3 This is a front view of the power generation device in this embodiment. Figure 4 This is a schematic diagram showing the arrangement of multiple annular drive rings in this embodiment. Figure 6 This is a top view of the multiple annular drive rings in this embodiment. As a further optimization, this embodiment has multiple annular drive rings, which are arranged layer by layer at equal intervals along the radial direction of the support. The multiple annular drive rings are coaxial with the vertical center line of the support. The length of the connecting arm 14 on the multiple annular drive rings gradually increases from the outside to the inside. The distance between the outer edge of the wave plate 5 on the multiple annular drive rings and the vertical center line of the support gradually decreases from the outside to the inside. The tension rope 15 passes through the connecting ring 17 on each annular drive ring layer by layer from the outside to the inside and is fixedly connected to the last connecting ring 17 on the innermost annular drive ring.

[0047] This embodiment utilizes a multi-stage wave-driven structure formed by arranging multiple annular drive rings at equal intervals layer by layer, achieving efficient capture and stable transfer of complex wave energy in strong wave sea areas. The structure employs multiple annular drive rings arranged layer by layer from the outside in, each layer capable of independently responding to wave impacts of different directions and intensities. Multi-stage coordinated output is achieved through a unified tension rope 15, thereby improving the overall energy conversion efficiency and operational stability of the power generation device.

[0048] The structure features multiple annular drive rings arranged in a nested, equally spaced pattern along the radial direction of the support frame. The centerlines of all annular drive rings are coaxial with the vertical centerline of the support frame, ensuring structural symmetry and stress balance in three-dimensional space. This coaxial arrangement allows each layer of annular drive rings to produce a uniform oscillation response when subjected to waves from any direction, preventing localized stress concentration or structural instability caused by eccentric forces. Furthermore, the equally spaced radial distribution helps optimize the overall structural space utilization, maximizing the number of wave-collecting units within the limited projected area of ​​the floating body and increasing the energy capture density per unit area.

[0049] The length of the connecting arms 14 on multiple annular drive rings gradually increases from the outside to the inside, meaning the outer connecting arms 14 are shorter and the inner connecting arms 14 are longer. This design overcomes the limitation of uniform length for all connecting arms 14 in a single-level drive structure, allowing the inner structure to have a greater stroke and leverage effect. When waves act on the longer inner connecting arms 14, even if the impact force on the wave-receiving plate 5 is small, a larger torque output can be generated through the extended lever arm, enhancing the response to low-amplitude, high-frequency waves. Simultaneously, the increasing length of the connecting arms 14, combined with the changing position of the wave-receiving plate 5, forms a gradient energy transmission path, which helps to gradually focus external disturbances to the central region, improving energy transfer efficiency.

[0050] The distance between the outer edge of the wave-receiving plates 5 on multiple annular drive rings and the vertical centerline of the support gradually decreases from the outside to the inside. This means that the outer wave-receiving plates 5 are widely distributed and cover a large area, enabling them to capture wave disturbances from a distance first. The inner wave-receiving plates 5 are concentrated within a smaller radius, making them more responsive to localized violent fluctuations or short-wavelength impacts. This outward-contracting wave-receiving plate 5 layout not only expands the overall effective wave-facing area but also forms a composite working mechanism of "wide-area energy capture - step-by-step focusing." The outer layer first intercepts large-area wave energy and initiates the initial drive, while the inner layer subsequently receives secondary fluctuations after refraction and reflection, supplementing additional kinetic energy, thereby achieving continuous capture of wave energy across the entire frequency band and in all directions.

[0051] In this embodiment, the tension rope 15 passes through the connecting rings 17 on each annular drive ring from the outside in, and is fixedly connected to the last connecting ring 17 on the innermost annular drive ring. This rope-threading method allows the tension rope 15 to sequentially connect all levels of annular drive rings, forming a continuous energy transmission link. When any annular drive ring swings up and down due to wave impact, its corresponding connecting arm 14 drives the connecting ring 17 to pull the tension rope 15. The resulting tension is superimposed along the tension rope 15 and finally transmitted to the generator 8. Since the tension rope 15 runs through all levels and is only fixed at the end, it can effectively contribute to the tension output regardless of which layer or multiple layers are simultaneously affected by waves. This avoids the risk of system shutdown due to the failure of a single annular drive ring, and significantly improves the continuity and reliability of power generation in random wave environments.

[0052] The power generation device in this embodiment constructs a multi-level, highly redundant, and adaptive wave energy capture system. The coaxial arrangement of the multi-layer annular drive rings ensures structural symmetry and dynamic balance. The combination of the increasing length of the connecting arm 14 from the outside to the inside and the decreasing position of the wave-receiving plate 5 forms a mechanical gradient distribution, which optimizes the torque transmission path. The series connection of the tension rope 15 realizes the integrated output of multi-level drive signals, enhancing the system's fault tolerance and energy integration efficiency.

[0053] This embodiment achieves a highly efficient response to multi-directional and multi-frequency wave disturbances in strong wave environments. By employing multiple coaxial, nested annular drive coils, and through the coordinated design of the connecting arm 14 length and the wave-receiving plate 5 position, the device ensures that some annular drive coils will generate effective movement under wave conditions of different wavelengths and incident angles. This solves the problems of narrow energy capture range and unstable output caused by the susceptibility to wave direction in traditional wave energy devices. Simultaneously, the tension rope 15 connects each layer of annular drive coils in series, ensuring that even if some layers of annular drive coils are not directly impacted, the remaining layers can still maintain the continuous operation of the generator 8. Therefore, it achieves the technical effects of increasing energy capture density, enhancing power generation continuity, and improving system stability.

[0054] Specifically, in this embodiment, there are, for example, three wave-driven structures (from the outside in: third-level wave-driven structure, second-level wave-driven structure, and first-level wave-driven structure). The top diameter of the annular drive ring in the second-level wave-driven structure is smaller than the top diameter of the annular drive ring in the third-level wave-driven structure, and the lower diameter of the annular drive ring in the second-level wave-driven structure is smaller than the lower diameter of the annular drive ring in the third-level wave-driven structure. The length of the connecting arm 14 in the second-level wave-driven structure is greater than the length of the connecting arm 14 in the third-level wave-driven structure. The distance between all wave-receiving plates 5 in the second-level wave-driven structure and the vertical center line of the support is less than the distance between all wave-receiving plates 5 in the third-level wave-driven structure and the vertical center line of the support. This allows the center of gravity of the overall structure of the power generation device to shift downward, which is beneficial for the overall stability of the power generation device during operation at sea.

[0055] Reference Figure 7 , Figure 7 This is an enlarged schematic diagram of point C of the power generation device in this embodiment. As a further optimization, in this embodiment, a U-shaped force-bearing connecting pipe 12 is fitted on the side of the connecting arm 14 away from the support. The two ends of the Y-shaped connecting rod 21 are fixedly connected to the U-shaped force-bearing connecting pipe 12. A cantilever connecting rod 11 is provided between the bottom middle of the U-shaped force-bearing connecting pipe 12 and the wave-receiving plate 5. One end of the cantilever connecting rod 11 is fixedly connected to the U-shaped force-bearing connecting pipe 12, and the other end is fixedly connected to the wave-receiving plate 5.

[0056] In this embodiment, a multi-point collaborative force-bearing system is constructed by introducing a U-shaped force-bearing connecting pipe 12 and a cantilever connecting rod 11, which significantly improves the strength and stability of the wave-driven structure under complex sea conditions. The overall scheme adopts a mechanical optimization design to ensure that the load can be evenly distributed among the components under wave impact, reducing local stress concentration and thus improving the durability and reliability of the system.

[0057] The U-shaped load-bearing connecting pipe 12, acting as a reinforcing member, is fitted onto the side of the U-shaped connecting arm 14 furthest from the support. Its material can be high-strength alloy steel or corrosion-resistant stainless steel, and its cross-sectional shape matches the outer contour of the U-shaped connecting arm 14 to ensure a tight fit. Reliable fixing is achieved through welding or bolting. This design not only enhances the overall rigidity of the end of the U-shaped connecting arm 14 but also effectively disperses localized stress concentration caused by wave impact, preventing fatigue cracks or loosening of the connection under long-term alternating loads.

[0058] The two branch ends of the Y-shaped connecting rod 21 are fixedly connected to the two side arms of the U-shaped force-bearing connecting pipe 12, respectively. The included angle design can be adjusted according to the actual force requirements to optimize the force transmission path. The Y-shaped connecting rod 21 can be made of high-toughness aluminum alloy or composite material, which reduces the overall weight while ensuring strength.

[0059] The cantilever connecting rod 11 is located at the bottom center of the U-shaped load-bearing connecting pipe 12. One end of the rod is welded to or integrally formed with the U-shaped load-bearing connecting pipe 12, and the other end is fixedly connected to the wave-receiving plate 5. The cantilever connecting rod 11 can be a straight rod or an arc-shaped rod structure. Its main function is to directly transfer the vertical wave impact force borne by the wave-receiving plate 5 to the U-shaped load-bearing connecting pipe 12 through the central support point. In addition, the presence of the cantilever connecting rod 11 changes the stress mode of the wave-receiving plate 5 from a cantilever beam to a combined structure of a simply supported beam and a cantilever, significantly improving the bending stiffness.

[0060] This embodiment achieves structural reinforcement of the connection area at the end of the U-shaped connecting arm 14. By adding a U-shaped force-bearing connecting pipe 12 to the outside of the connecting arm 14 and introducing a Y-shaped connecting rod 21 to form a multi-point force transmission path with the cantilever connecting rod 11, the impact load of the wave-receiving plate 5 can be more evenly distributed to the connection structure when subjected to periodic wave impacts, reducing the phenomenon of local stress concentration. This solves the technical problem of easy loosening and breakage of the connection part in a strong wave environment, and achieves the technical effect of enhancing structural reliability and extending the service life of the device.

[0061] Reference Figure 5 , Figure 9 , Figure 5 This is an enlarged schematic diagram of point B of the power generation device in this embodiment. Figure 9 This is an enlarged schematic diagram of point D of the power generation device in this embodiment. As a further optimization, in this embodiment, the connection points of adjacent connecting arms 14 are respectively fitted with edge sealing clamps 13. The connection points of the edge sealing clamps 13 and adjacent connecting arms 14 are connected by fasteners. A connecting shaft 20 is horizontally provided directly above the top of the edge sealing clamp 13. Clamping platforms 22 are fixed at both ends of the connecting shaft 20 and are perpendicular to each other. The clamping platforms 22 are fixedly connected to the top of the edge sealing clamp 13. A ring 23 is fitted on the connecting shaft 20 and is rotatably connected to it. One side of the ring 23 is fixedly connected to the bracket.

[0062] This embodiment addresses the problem of loosening, accelerated wear, or deviation of the motion trajectory in the hinged structure between the annular drive ring and the support under long-term wave loads. It proposes a technical solution to enhance connection stability while ensuring swing flexibility. This solution improves the reliability of the connection under dynamic loads by structurally reinforcing the connecting nodes of adjacent U-shaped connecting arms 14 and introducing a relatively rotatable support connection mechanism.

[0063] In this design, adjacent U-shaped connecting arms 14 are secured in a wrapping manner at their intersection area using edge-sealing clamps 13. These clamps 13 are made of high-strength metal sheet, stamped with an inner cavity shape that matches the outer contour of the U-shaped connection, allowing them to fit tightly against the mating area of ​​adjacent connecting arms 14. The edge-sealing clamps 13 are then fixed to the mating area of ​​the adjacent connecting arms 14 using bolts or other detachable threaded fasteners. This not only improves the overall rigidity of the connection area and prevents metal fatigue cracking caused by repeated bending, but also facilitates disassembly and replacement during later maintenance. This design is particularly suitable for durability requirements under frequent alternating stress conditions in high-wave sea areas.

[0064] A horizontally arranged connecting shaft 20 is provided directly above the top of the edge sealing clamp 13. Clamping platforms 22 are fixedly connected to both ends of the connecting shaft 20. The clamping platforms 22 have a plate-like structure and are set perpendicular to the connecting shaft 20 to improve torsional resistance. The other end of the clamping platform 22 is welded to the top of the edge sealing clamp 13 or connected by bolts.

[0065] A ring 23 is fitted onto the connecting shaft 20. A rolling bearing or sliding sleeve is provided between the inner wall of the ring 23 and the connecting shaft 20 to achieve relative rotational engagement between them. The outer side or sidewall of the ring 23 is fixedly connected to the bracket via a support rod, connecting plate, or other structure, thereby restricting the swing freedom of the entire annular drive ring to a single rotational freedom around the connecting shaft 20. This connection method allows the annular drive ring to swing freely up and down around the connecting shaft 20 when impacted by waves on the wave plate 5, while effectively suppressing lateral displacement and torsional vibration, preventing deviation of the traction direction of the tension rope 15, and improving energy transfer efficiency.

[0066] In addition, the rotating pair formed by the connecting shaft 20 and the ring 23 can be made of corrosion-resistant materials, such as a stainless steel shaft with a self-lubricating copper-based bushing, which is suitable for long-term operation in a seawater environment.

[0067] In this embodiment, the edge-sealing fixing clamp 13 enhances the structural integrity of the connection node between adjacent connecting arms 14, effectively preventing loosening or breakage caused by continuous swinging. Simultaneously, a stable rotating hinge point is formed by setting a rotating support structure above the edge-sealing fixing clamp 13, consisting of a connecting shaft 20, a clamping platform 22, and a ring 23. This allows the annular drive ring to swing flexibly within a defined trajectory, ensuring smooth wave-driven motion while avoiding swaying and deviation during movement. This, in turn, ensures consistent force direction and smooth transmission of the tension rope 15, improving the reliability and service life of the power generation system.

[0068] As a further optimization, in this embodiment, the longitudinal section of the wave-receiving plate 5 is arc-shaped, the centerline of the wave-receiving plate 5 is located on the lower side of the arc, and the centerline of the wave-receiving plate 5 intersects perpendicularly with the centerline of the annular drive ring.

[0069] In this embodiment, the wave-receiving plate 5 is designed as an arc shape, and combined with the perpendicular intersection of its center line and the center line of the annular drive ring, it realizes efficient capture and stable transmission of wave energy in multiple directions.

[0070] The longitudinal section of the wave-receiving plate 5 is arc-shaped, meaning that the cross-sectional shape obtained by cutting along the height of the wave-receiving plate 5 is a circular arc or a near-circular arc curve. This arc-shaped structure is an upwardly convex curved surface, which can enhance the ability to withstand the impact force of waves from bottom to top. This arc-shaped surface has excellent hydrodynamic characteristics, which can effectively guide the direction of water flow under the action of waves, reduce local turbulence and pressure concentration, thereby improving energy conversion efficiency. In addition, the arc-shaped surface generates an upward resultant force component when impacted by wave crests, which is more conducive to driving the connecting arm 14 to generate a swinging motion around the hinge point, thereby pulling the tension rope 15 to realize the power generation action.

[0071] The centerlines of the wave-receiving plates 5 intersect perpendicularly with the centerline of the annular drive ring, meaning that the centerlines of the wave-receiving plates 5 are aligned with the radial direction of the horizontal projection circle of the annular drive ring, and the two form an orthogonal relationship in three-dimensional space. This arrangement ensures that each wave-receiving plate 5 faces the direction of the incoming wave, maximizing its wave-facing area. This allows the waves to be uniformly and effectively captured and converted into mechanical motion, regardless of their direction of incidence, as long as they are within the plane of the annular drive ring. This perpendicular intersection also ensures the symmetry of multiple wave-receiving plates 5 when evenly distributed around the center of the support, helping to counteract lateral unbalanced moments and preventing the device from twisting or tilting due to eccentric loading.

[0072] In this implementation, the wave-receiving plate 5 maintains structural strength while possessing excellent hydrodynamic performance and directional adaptability. The arc-shaped longitudinal section of the wave-receiving plate 5 enhances the absorption efficiency of vertical wave kinetic energy, while the perpendicular intersection of its centerline with the centerline of the annular drive ring ensures consistent and stable response under multi-directional wave excitation. For example, in practical applications, when waves impact the wave-receiving plate 5 from different directions, the arc-shaped longitudinal section smoothly guides the water flow and generates a combined force of upward buoyancy and impact reaction at the bottom of the plate, propelling the connecting arm 14 to swing upward. Simultaneously, because the centerline of the wave-receiving plate 5 intersects perpendicularly with the centerline of the annular drive ring, each wave-receiving plate 5 maintains the optimal wave-facing posture. Regardless of changes in the wave incident angle, it can efficiently stimulate the synchronous or alternating swinging behavior of the connecting arm 14, thereby continuously pulling the generator 8 shaft through the tension rope 15 to achieve stable power output.

[0073] This embodiment enables the wave-receiving plate 5 to effectively guide water flow and reduce turbulence loss under multi-directional wave impact, solving the problems of slow response and uneven force distribution of traditional flat-plate wave-receiving structures in multi-directional waves. Furthermore, because the centerline of the wave-receiving plate 5 intersects perpendicularly with the centerline of the annular drive ring, each wave-receiving plate 5 can maintain the optimal wave-facing posture under any wave incident angle, avoiding the risk of device instability due to off-center loading. Combined with the synergistic effect of the arc-shaped longitudinal section of the wave-receiving plate 5 intersecting perpendicularly with the centerline, the energy capture capability and operational reliability of the device in strong wave sea areas are significantly enhanced, achieving the technical effects of improving power generation efficiency and extending equipment service life.

[0074] As a further optimization, the support in this embodiment includes: an upper disk 4, a lower disk 7, and multiple main connecting rods 9. The upper disk 4 is horizontally positioned directly above the lower disk 7 and coaxial with its center line. Multiple main connecting rods 9 are equally spaced and arranged around the upper disk 4 and the lower disk 7. One end of each main connecting rod 9 is fixedly connected to the upper disk 4 and the other end is fixedly connected to the lower disk 7. A generator 8 is fixed on the upper side of the lower disk 7. Multiple floating cylinders 3 are equally spaced and fixed around the outside of the upper disk 4. One end of the mooring cable 6 is connected to the middle of the bottom of the lower disk 7.

[0075] In this embodiment, the support frame, consisting of an upper disk 4, a lower disk 7, and multiple main connecting rods 9, forms a spatial truss-like support frame, arranged vertically and coaxially symmetrically. The lower disk 7 supports the generator 8 and other transmission components, and serves as the connection foundation for the wave-driven structure. The upper disk 4 and the lower disk 7 are rigidly connected by multiple circumferentially distributed main connecting rods 9, forming a stable three-dimensional spatial structure with high bending and torsional stiffness, effectively dispersing wave impact loads and preventing local stress concentration.

[0076] The upper disk 4 and the lower disk 7 are coaxial and parallel to each other, ensuring symmetrical mass distribution and buoyancy distribution of the entire device and reducing rotational torque caused by eccentric loading. The main connecting rods 9 are arranged at equal intervals along the circumference, with a maximum of 3 to 8 rods. They are made of high-strength metal materials such as Q355B or aluminum alloy 6061-T6, and their cross-sections can be circular, square, or tubular, meeting structural strength requirements while also considering lightweight design. The main connecting rods 9 are connected to the upper and lower disks by welding or high-strength bolts, ensuring reliable connection while facilitating on-site assembly and maintenance.

[0077] The generator 8 is fixedly installed on the upper surface of the lower disk 7, close to the central area, which concentrates the power equipment in the lower part of the structure. This helps to lower the overall center of gravity of the entire power generation device, enhance its attitude stability in strong wave environments, and reduce the risk of overturning.

[0078] Specifically, a supporting ring 2 is fitted around the outer side of the upper disc 4 and is coaxial with its center line. Multiple float tubes 3 are evenly spaced and fixed around the outer edge of the supporting ring 2. The supporting ring 2 improves the stability of the float tubes 3 installation and ensures that they do not loosen during violent shaking. The float tubes 3 are usually made of well-sealed high-density polyethylene (HDPE) or fiberglass, which have excellent corrosion resistance and long-term buoyancy retention capabilities. These float tubes 3 not only provide sufficient positive buoyancy to maintain the floating state of the device, but also form a larger buoyancy center radius through their extended layout, thereby increasing the restoring moment and further improving the anti-overturning performance.

[0079] One end of the mooring cable 6 is connected to the center of the bottom of the lower disc 7. This connection point is located below the geometric centerline of the entire structure, reducing the additional bending moment caused by eccentric traction. The mooring cable 6 can be made of high-strength synthetic fiber rope or galvanized steel wire rope to ensure that the power generation unit can maintain basic positioning stability under complex sea conditions.

[0080] Specifically, in this embodiment, a central connecting rod 18 is vertically fixed at the bottom of the lower disk 7. The central connecting rod 18 is coaxial with the center line of the lower disk 7. One end of the mooring cable 6 is fixedly connected to the lower end of the central connecting rod 18, which can prevent the mooring cable 6 from getting tangled with the tension rope 15 or the connecting arm 14.

[0081] The various components of the aforementioned support structure work together to create a stable configuration that is "lighter at the top and heavier at the bottom, with the outer layer floating and the inner layer stable." The lower layer concentrates key electromechanical equipment, while the middle section transmits loads and maintains structural rigidity through multiple main connecting rods 9. This layout is particularly suitable for sea areas with strong waves, and can significantly improve the safety and reliability of system operation while ensuring sufficient power generation capacity.

[0082] This embodiment achieves an optimized design of the support system for the offshore power generation unit. By adopting a truss structure composed of upper and lower double-layer discs and annular main connecting rods 9, and arranging the generator 8 on the lower layer and the floating cylinders 3 distributed on the outer perimeter of the upper layer, combined with the mooring method of vertical anchoring in the middle, the problems of traditional floating platforms being prone to capsizing in strong wind and waves, insufficient structural strength, and unreasonable equipment layout are solved. This achieves the technical effect of improving the overall structural stability, enhancing anti-interference ability, and ensuring continuous and stable power generation.

[0083] As a further optimization, in this embodiment, the diameter of the upper disk 4 is larger than the diameter of the lower disk 7.

[0084] In this embodiment, the overall mass distribution and buoyancy distribution of the device are optimized by differentiating the diameters of the upper disk 4 and the lower disk 7. The upper disk 4, as the main load-bearing platform at the top of the device, has a larger diameter, which allows components such as the floating cylinder 3 and photovoltaic panel 1 to be evenly distributed over a larger area, thereby expanding the horizontal projected area and buoyancy area of ​​the upper structure. The lower disk 7, on the other hand, houses key equipment such as the generator 8 and has a smaller diameter to reduce the underwater wave-facing area of ​​the overall structure and reduce the direct impact of waves on the bottom components.

[0085] The inverted conical geometry of the support frame, which is wider at the top and narrower at the bottom, helps improve the hydrodynamic stability of the device in strong wave environments. Compared with structures with equal diameters at the top and bottom or smaller diameters at the top and wider diameters at the bottom, this shape can effectively disperse wave loads, avoid local stress concentration, and accelerate the speed at which the structure above the water surface returns to its equilibrium posture during wave recovery. This makes the center of gravity of the power generation device lower, which helps the device have stronger stability when subjected to wave impacts and prevents it from being overturned by waves.

[0086] This embodiment optimizes the center of gravity-mass-buoyancy distribution pattern of the device by adjusting the diameter relationship between the upper and lower disks 7, solving the technical problem that traditional offshore power generation devices are prone to capsizing and have poor stability under strong waves, thereby achieving the technical effect of enhancing the overall machine's anti-roll capability and operational safety.

[0087] Reference Figure 2 , Figure 2 This is an enlarged schematic diagram of point A of the power generation device in this embodiment. As a further optimization, in this embodiment, a limiting wheel 16 is vertically provided on the upper side of the lower disk 7 and is located on the side where the generator 8 is connected to the tension rope 15. The limiting wheel 16 is rotatably connected to the lower disk 7 through a rotating shaft, and the tension rope 15 is wound around the limiting wheel 16.

[0088] In this embodiment, the limiting wheel 16 is a guide component used to guide and constrain the movement path of the tension rope 15, making the pulling or retraction of the tension rope 15 smoother. The limiting wheel 16 can be a grooved roller or a smooth roller without grooves, and can be a V-grooved roller to enhance the positioning capability of the tension rope 15. The installation direction of the limiting wheel 16 is perpendicular to the plate surface of the lower disc 7, that is, arranged in a vertical direction, to ensure that the tension rope 15 maintains a stable transmission angle during the up-and-down reciprocating pulling process, avoiding lateral deviation or jumping off. The limiting wheel 16 is installed on the upper side of the lower disc 7 through a central rotating shaft, so that the limiting wheel 16 can rotate freely under the traction of the tension rope 15, thereby converting sliding friction into rolling friction and significantly reducing transmission resistance.

[0089] After the tension rope 15 is led out from the output end of the generator 8, it first wraps around the outer circumference of the limiting wheel 16 and then extends to the wave-driven structure. Since the limiting wheel 16 is located in the vicinity of the connection point between the generator 8 and the tension rope 15, its position layout can effectively control the direction of the initial section of the tension rope 15, preventing stress concentration or increased local wear due to sudden angle changes. The tension rope 15 and the limiting wheel 16 have a flexible contact. As the connecting arm 14 swings up and down, the tension rope 15 is alternately pulled and retracted, and the limiting wheel 16 rotates synchronously to achieve a smooth transition.

[0090] As an alternative implementation, the wheel body of the limiting wheel 16 can be made of high-strength engineering plastics such as polyoxymethylene (POM) or fiber-reinforced nylon, which provides sufficient load-bearing capacity while reducing overall weight. Alternatively, it can be made of metal such as 45# steel or stainless steel, with a wear-resistant rubber layer covering its outer periphery to further enhance the protection of the tension rope 15. In addition, a rolling bearing or an oil-impregnated bushing can be installed between the pivot and the limiting wheel 16 to ensure rotational flexibility and extend service life.

[0091] In this embodiment, the tension rope 15 always travels along a preset trajectory during reciprocating motion, avoiding the risk of wear, jamming, or even breakage caused by swaying or angular deviation. Simultaneously, rolling friction replaces sliding friction between the tension rope 15 and the limit wheel 16, reducing energy loss and starting resistance, and improving transmission efficiency. Furthermore, this structure also serves as a tensioning aid, helping to maintain stable working tension of the tension rope 15, thereby ensuring uniform force distribution at the input end of the generator 8, improving the sensitivity of the power generation response and the reliability of system operation.

[0092] As a further optimization, in this embodiment, multiple photovoltaic panels 1 are fixedly arranged on the upper side of the upper disk 4, and the photovoltaic panels 1 are arranged horizontally.

[0093] In this embodiment, the upper surface of the upper disk 4 is a flat or nearly flat platform with sufficient structural strength and corrosion resistance. It is typically made of high-strength aluminum alloy, weathering steel, or composite materials and is used to support and fix multiple photovoltaic panels 1. The photovoltaic panels 1 are evenly distributed in an array on the upper surface of the upper disk 4, that is, arranged regularly along the circumference and radial direction to form a solar energy receiving array covering a certain area. This array layout can be optimized according to the angle of illumination, latitude of the sea area, and seasonal changes to achieve maximum solar radiation capture efficiency. Each photovoltaic panel 1 can be firmly installed on the upper disk 4 by bolts, welding, or bonding to ensure long-term stable operation in the high humidity, high salt spray, and strong vibration environment at sea.

[0094] This application realizes the integration of photovoltaic power generation function in a power generation device operating in strong wave sea areas by making full use of upper space resources. The horizontally arranged photovoltaic panel array 1 is fixed on the upper disk 4, which does not affect the working space of the wave energy capture structure below, and can stably obtain solar energy. The two power generation methods share the same floating platform and anchoring system, which significantly improves the energy output density per unit sea area, forming a multi-energy integrated system of solar energy and wave energy synergistic complementarity, and enhancing the device's comprehensive power supply capacity and economic feasibility.

[0095] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
